It's the finals and three bakers remain standing:
Sabrina Degni,
Vandana Jain and
Linda Longson, who are vastly different in their baking approach. The judges are looking for the bakers to incorporate all that they have learned since being in the tent to the finale challenges. For the signature challenge, the bakers will have to make twelve each of two different varieties of mini-mousse cakes - which must, by its nature, contain a sponge/cake/cookie base component - in two and a half hours. The main issue is the amount of stabilizing agent, usually gelatin, used in the mousse: too little and the mousse won't set, too much and the mousse will be rubbery. For the technical challenge, the bakers will have two hours twenty minutes to make a pear charlotte. Many things can potentially go wrong as the charlotte has several different components which are combined to make one spectacular looking dessert. For the final bake, the showstopper, the judges believe it is a fitting end to ask the bakers to make a wedding cake with at least three tiers in four hours.
